and bolts 75. licaring part 31 is held yieldingly central by means of several springs 34 fastened by screws 33. It will thus be seen that one of the bearings (31)) is a floating bearing capable of not only yielding laterally bjit of changing its axial alinen'ient, whereas the other bearing (51) is a stepped beii ring fixed axis and permitted to have only an oscillating movement. This combination of bearings insures more accurate response 'to de-' viations in the axis of rotation of the basket due to unbalance or other causes. A cut-out through which the part below thebasc may project. can be made in the floor 59 and ceiling 60, aiid the base 4 set on the joists 61, as shown, or a well can he made in the cement floor of the drying room and the stays at fasteneddirectly to the base 4 which is preferable to the plan shown in the drawing Fig. 2.

The pulley is held slidaQ-ly but non-rotatablv on the shatt. by means of a her 37 and keyway 2Q. The lower part of shaft 5?, sets in a bronze bushing 52 with a steel end-bearing 52'. The upper part of bearing member 51 forms a bearing 51 for shaft 7. In this hearing is a cut'-out 53!) for pinion 49 to slide. laterally, in and out of mesh with the rack 471m the shaft. llere also is the pivot part 48 for pawl 46 on shaft 45.

The tub A is positively rotated by means of belt 36 and pulley 37. The outer tub P is carried by inner tub serving a. a friction clutch. V

Minor details of constructioncan .be varied from those disclosed without departing from the principles of the invention.
